I've never been too good at arguments. I walk out of the conversation easily. Hands down. It's not that I don't know how to defend myself, nor am I bad at proving people I'm right.
It might just be because I'm tired. Tired of having to mouth off words that I know will lead to nothing but pain and more trouble. I've worn myself out that mentally, I can't seem to get my whole system to work like what it used to.
Although, it's a lot different when you're having a fight with someone you love. It tends to get a bit complicated.
You try to hold yourself back from saying too much that as you try to reason out, you end up losing as you give up the fight. Thinking that if you'd go on with it, your ego wins but then you'll lose the one you love. Never mistake your pride to something you think losing someone important is worth it.
You ask if this has something to do with what had recently happened. You're right. It's just a little misunderstanding that was a bit my fault. I know well enough not to push it. I did apologize, but she's still upset.
